In modern usage, the word casino describes a large entertainment facility that offers a variety of gambling games. Usually, such facilities offer many different types of table games, slot machines, video poker and lottery-type games. Some casinos also have hotels, restaurants, non-gambling game rooms and other amenities to attract visitors. Some are enormous, with impressive size and beautiful decor, while others are smaller but still contain a large number of games.
Something about the high stakes and glamour of casino gambling seems to encourage people to cheat, steal or scam their way into a jackpot. For this reason, casinos spend a great deal of time and money on security. Modern casinos typically employ a physical security force to patrol the building, as well as a specialized department that supervises casino games using closed circuit television and other technology.
The first casinos grew out of small clubhouses for Italians who visited for social occasions and to play various games of chance. By the second half of the 19th century, casino was an established name in Europe for a collection of gaming or gambling rooms, especially those found in Monte Carlo.
Local economies get a boost from the money that gamblers put into casinos. That money gets spent on food, drinks and hotels, and will often be re-invested in the economy through other purchases. Even if the majority of bettors lose their money, casinos can make a gross profit because they have built-in advantages that ensure their profitability. These advantages, called the house edge, are calculated mathematically and are a function of the rules and mathematics of each game.
